R
Fix the component by first soldering two diagonally- opposite end leads. Use only a low voltage soldering iron (less
than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a
dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
